GLASS-CUTTING APPARATUS- reference being had to the accompanyingdrawings, forming part of this specification,

in which Figure 1 is a plan view of a glass cutting table and cuttingapparatus embodying our invention. Fig. 2 is a side elevation of thewill now same. Fig. 3 is a transverse vertical section, and Fig. 4 is adetail view.

Our invention has relation to glass cutting apparatus, and is designedtoprovide means ofsimple and efiicient character which can be readily usedin connection with a glass cutting table for the accurate cutting ofplates or sheets of glass.

Our invention may be made in the nature of an attachment which can beapplied to the usual glass cutting tables, in place of the cutting ruleordinarily employed.

The nature of our invention will be best understood by reference to theaccompanying drawings, in which we have shownthe preferred embodimentthereof, and which be described, it being premised, however, thatvarious changes can be made in the details of construction andarrangement of the severalparts without departing from thespirit andscope of our invention.

In these drawings the numeral 2 designates a glass cutting table whichmay be of the usual construction having a series of pins 3 at one of itslongitudinal edges which are usually provided for engagement with ,oneend of the usual cutting rule; and aseries of laterally projecting pins4 at the opposite edge for engagement with the other end portion of saidrule. In the operation of the table with our attachment applied thereto,the pins 3 are not used, but may be retained to permit the table to beoperated in the usual manner, if desired.

5 and 6 designate two parallel rods which Specification of LettersPatent.

are supported transversely of the table upon the movablebrackets 7 and8. The-bracket 7 is at one slde of the table and is provided at itslower end with an inwardly extending arm'7 having a shoe portion 7adapted to slide on a track bar 9. Preferably, the shoe Patented Apr.11, 191% Application filed July 2, 1914. Serial No. 848,566. I

The bracket 7 isalso preferably provlded Wltl'l. a guard arm'lO which extends underneaththe track bar 9 and. prevents disengagement of the shoe 7 with said bar.The bracket 8 is-at the opposite side of the table and has the inwardlybent arm 8 carrying the shoe portion 8 which 7 engages a track bar 11,similar to the bar 9.

esigned to beheld in-engaging posi- 1 12 is a guard member which issimilar to the guard member 10 at the opposite side.

v 13 designates a cutter carriage which is sleeved upon, and mounted tomove trans.-

versely of the table on the parallel rods 5 and 6. This carriage carriesa cutting tool 14 of any suitable character. The details of the cuttercarriage and cutter form no part of the present invention, and need notbe described in detail, as any suitable arrangement of carriage-andcutter may be employed. The carriage and cutter herein shown form thesubject matterof the pending application of -.John Waterloo and GeorgeW.Klages, Serial No. 842,437, filed June 2, 1914.

The brackets 7 and 8, together with the ide rods, can be movedlongitudinally of the table 2 to any desired position, and may be lockedin theset position by any suitable means. In the drawing this look isshown as consistingof a lever catch 15 pivoted to the bracket 7 andadapted to engage be-- tween any two ofthe lateral pins 4, or to impingeagainst any As shown, the catch 15. is tion by hand.

It is desirable that the apparatus shall be so constructed and arrangedas to be capable of very accurate work. It may happen, es-:

one of said pins, at

pecially after some wear, and as the rods 5 and 6 are of oonslderablelength, that in m'ovingithe brackets 7 and 8 along the table one. of thebrackets would move slightly more than the other, so that the rods 5 and6 would not be strictly perpendicular to the longitudinal axis of thetable. To guard against this possibility, we preferably employ a guideor equalizing device which will insure a constant perpendicularity ofthe guide rods 5 and 6 with respect to the longitudinal axis of thetable. This guide or equalizing device may conveniently consist of twowires 17 and 18. The wire 17 is connected at one end to the bracket 8 atthe point 19 and extends thence forwardly around a sheave or pulley 20,thence 15' obliquely backward across the table around a similar sheaveor pulley 21 to the diagonally opposite corner portion of the table, andthence forwardly where it is connected to the bracket 7 at the point 22.The wire 18 is attached to the bracket 7 at the point 23, extendingthence forwardly around a sheave or pulley 24;, thence diagonally acrossthe table to the rear end thereof and around readily a sheave or pulley25, and thence forwardly to the-bracket 8 to which it is connected at26. These wires are preferably of material which will have a minimumamount of stretch, such as piano wire. It will be seen. that when theseequalizing wires are properly applied they will insure a true parallelmovement of the brackets, thus insuring the proper positioning at alltimes of the cutter carriage carrying rods 5 and 6. i

The advantages of our invention will be apparent, since it provides avery simple form of attachment by means of which glass sheets of varioussizes and lengths can be readily and accurately out upon the ordinarytable, the attachment taking the place of the old cutting rule. Thesecutting rules require to be lifted manually fromone position to another,whereas the'present attachment can be readily slid from one position toanother by temporarily releasing the lever catch 15.

When it is desired to use the table with a cutting rule in the ordinarymanner the attachment can be readily removed, or moved,

to a position where it is entirely out of the way and will not in anyway interfere with the use of the table in the ordinary way; By settingthe cutter longitudinally of the table instead of transversely, sheetsmay be cut longitudinally by simply moving the bridge lengthwise of thetable and causing the cutter to operate during such movement.

What' we claim is:

1. The combination with a glass cutting table, of a bridge mounted tospan the table in one direction and to be moved over the table in adirection at substantially right angles to its span, guides supported bygreater than the other and the table and on which said bridge ismounted, said guides being separated from the edges of the table, aholding device carried by the bridge, means on the table to cooperatewith the holding device, and a glasscutter movably mounted for travel onthe bridge; substantially as described.

2. The combination with a glass cutting table, of a bridge mounted totraverse said table in one direction, a cutter carriage mounted on thebridge to traverse the table in a direction at substantially rightangles to the movement of the bridge itself, and an equalizer connectedto the bridge to secure parallel movement thereof, substantially asdescribed.

3. The combination with a glass cutting table having one horizontaldimension having a plurality of stops, of a cutter guide mounted totraverse said table longitudinally thereof and having means forcooperating with the different stops, the table having tracks locatedbelow its top and upon which the said guide ismounted; scribed.

The combination with a glass cutting table, of a bridge spanning thetable in one direction and movable over the table surface in a directionat substantially right angles to that in which the bridge extends, andhaving end portions which extend to points below the level of thesurface of the table, tracks engaged by said end portions, acutter-carriage mounted to travel on the bridge, a cutter on saidcarriage, and equalizing means connected to said end portions of thebridge below the level of the surface of the table for insuring parallelmovement of the bridge; substantially as described.

5. The combinationwith a glass cutting table, of a bridge mounted tospan the table in one direction and having end supports whichextenddownwardly below the table top, guides fixed relatively to the table andupon which the end supports are movably mounted, and a cutter arrangedto travel on said bridge; substantially as described.
